Telephony and Conferencing

Windows 2000 Professional provides support for telephony and conferencing applications in a variety of telecommunications environments, including device support for modems, network adapters, and other telecommunications devices used by applications.

Function calls made by the Telephony Application Programming Interface, also known as Telephony API (TAPI), provide the foundation for the deployment of telephony and conferencing applications. TAPI abstracts the details of the underlying telecommunications network, allowing applications and devices to use a single command set. TAPI-enabled applications and devices can operate in a variety of telecommunications environments, including traditional analog switched networks, Private Branch Exchange (PBX) phone networks, and Integrated Services Digital Network (ISDN). TAPI further expands telecommunications support through the IP-based telephony, enabling telecommunications functions through a private intranet or over the Internet.
